Cool Stack 1.3 is here
Posted June 11, 2008on:
It’s finally here. Before you download the release, please do read the documentation. It’s over a month late, but hopefully the features will compensate for the delay.
Almost every single component in the stack has been upgraded. Two new packages, CSKpython and CSKnginx have been added. And yes – the python package does include mod_python too.
You can read about the full list of changes in the Changelog.
Significant changes have been made to the ruby package. In addition to the upgrade to ruby1.8.6p114, we include a number of gems, notably mysql, postgres and mongrel. It should also be easy to install any new gem that requires native compilation using gcc – this should just work out of the box. A word of caution if you’re running ruby on SPARC. Please DO NOT use gcc. If you’re importing native gems, take the extra step of installing Studio 12 and use the rbconfig.studio instead (simply rename it to rbconfig.rb after saving the current one). This file is located in /opt/coolstack/lib/ruby/1.8/sparc-solaris2.10.
There have also been significant performance enhancements for ruby made in this release. By changing compiler flags, we have measured 20-30% improvement. In addition, SPARC-specific patches (which are now in ruby 1.8.7) improve performance a further 8-15%. If you are a ruby user, let us know your experiences. I’d love to hear of any performance changes you see as well.
In a future post, I’ll share some performance results on the AMP stack. But for now, please try this release and let us know what you think via the forum or comments on this blog.
Cool Stack installation in Zones
For users who have installed Cool Stack in zones, I know the upgrade is a painful process. As I mentioned earlier, we do hope to fix this situation by allowing upgrade installs in future. But some users have found solutions on their own. In particular, I found this post in the forum interesting. Scroll down to reply 19.
